People rating this book under 4 stars are not grasping the overall messages in this book. Susan has been coddled her entire life, without the knowledge that she's not "normal". She doesn't have a lick of anxiety, because she lives in the moment, enjoys the small things and finds joy in simplicity. When she finds out she's been deceived, by the ones she trusted and loved, she has to think for the first time. She finds that people all over the world try their hardest to NOT think, to not have anxiety and stress over things we cannot control. She finds that absurd and calming that people strive to be in a state she is in most of the time.
The human experience is complex. There are wars, famine, suffering and hardships but there is also joy, happiness, pleasure and satisfaction in things we do, and experience.
I loved this story, and while thinking, being innovative and creating is part of our lives as well, we should also strive to be a bit more like Susan.
